Who it suits / who it doesn't

Good fit for

Needs a consultation first

Thermage is less about 'pulling a sagging face upward' and more about 'tightening the skin layers to restore firmness.' If the jawline sags significantly, it is usually combined with a deeper lifting treatment such as Ulthera.

What is Thermage FLX? — Tightening dermal collagen with radiofrequency

Thermage uses radiofrequency (RF) energy to heat the dermis evenly over a wide area. Heated collagen fibers contract right away, giving a tightening feel, and as the skin recovers, new collagen forms and firmness improves gradually.

FLX is the name of the generation of Thermage device most widely used today. Compared with earlier generations, the tip covers a larger area so treatment time is shorter, and the device senses the skin with each shot to adjust the energy.

ItemThermage FLX

Difference between face Thermage and eye Thermage (eye tip)

Face ThermageEye Thermage
Tip usedFace/body tipSmall eye-specific tip (eye tip)
AreasCheeks, jawline, forehead, under the chin, etc.Upper eyelids, under the eyes, outer corners of the eyes
Best forOverall firmness, skin texture, fine linesFine lines around the eyes, a drooping-lid feeling, fine texture under the eyes
PreparationNumbing creamNumbing cream + protective eye shields

The skin around the eyes is very thin, so it is hard to treat with regular lasers or ultrasound lifting. Thermage offers a dedicated eye tip that can treat even over the eyelid. Many people have the face and eye area treated on the same day.

For eye treatment, protective eye shields are worn. If you arrive wearing contact lenses, they must be removed before treatment, so please bring glasses or a lens case.

What is a 'shot'? — Why results differ even with the same Thermage

With Thermage, each time the tip touches the skin and delivers energy counts as 1 shot. Each genuine tip has a set number of shots, so the shot count of the tip used reflects the amount of treatment.

How to check a genuine tip — see it with your own eyes

A Thermage tip is a single-use cartridge used for one person only, and the device recognizes the tip and records the remaining shots. That is why the key check is whether a new, genuine tip is opened in front of you.

  1. 1
    Before treatmentconfirm the quote lists the device (Thermage FLX), tip type (face/eye) and shot count.
  2. 2
    Opening the tipask for a sealed new tip package to be opened in front of you. If it is already open or already attached to the device, ask for an explanation.
  3. 3
    Authenticity checkyou can ask to see the authentication marks on the package and tip, such as product information or a QR code.
  4. 4
    Shot count on screenonce the tip is connected, the screen shows the shot count. Check the total before starting and that the shots used afterward match the quote.
  5. 5
    After treatmentyou may also ask to see the used tip again before it is discarded.
On the day, your KBEAU manager helps with interpretation and with checking the tip opening, authentication marks and the shot count screen. Asking to verify authenticity is every patient's right, so don't feel awkward about it.

How painful is it? — Cooling and vibration

With each shot, a 'brief hot' feeling passes in about 1–2 seconds. Thermage FLX has a cooling function that chills the skin surface before, during and after energy delivery, and a vibration function that distracts from the sensation, which reduces pain.

Combining with Ulthera — deep layer and skin layer together

Ulthera uses focused ultrasound to pull the deep fascia layer (SMAS) and lift sagging, while Thermage tightens the dermis with radiofrequency to improve firmness and texture. Because they work at different depths, many people with both sagging and loss of firmness have the two treatments on the same day (often called 'Ul-Thermage').

CombinationGood fit for
Thermage aloneFine lines, eye area and skin texture are the main concern, with little cheek volume
Ulthera + ThermageBoth sagging and loss of firmness; want one major session per year
Thermage + skin boosterWant firmness plus better inner hydration and glow
When combined, the deeper Ulthera is usually done first and the skin-layer Thermage afterward. The order and intensity are decided by your doctor after examination.

Treatment day step by step

  1. 1
    Consultation & design (20–30 min)the doctor checks skin thickness and areas of concern and sets the shot count for each area.
  2. 2
    Cleansing & numbing cream (30–40 min)contact lenses and makeup are removed.
  3. 3
    Genuine tip checkthe new tip is opened, authentication marks are checked, and the shot count screen is confirmed.
  4. 4
    Treatment (40–90 min)a single-use grid sheet is placed on the face and shots are delivered square by square. For the eye area, protective shields are worn first.
  5. 5
    Soothing care, then head outmany people can go straight back to daily activities and sightseeing.

What to expect after treatment

Downtime is minimal, but redness or swelling can last longer depending on your skin. If you have an important event, it's best to have it done 2–3 months beforehand.

Sample trip schedule

The air on a plane is dry, so bring a moisturizer. For 1–2 weeks after returning home, avoid strong exfoliation, hot saunas and other laser treatments, and if anything seems off, send a photo to your manager.

Frequently asked questions

What concerns does Thermage help with?
It often suits 'skin layer' concerns such as loss of firmness, fine lines, enlarged pores and eye wrinkles. If the jawline sags significantly, a deeper lifting treatment such as Ulthera is considered alongside it.
When will I see results?
You may feel slight tightening right after, and the main change appears over 2–3 months as new collagen forms.
How long do results last?
Usually around 6 months to 1 year, but it varies a lot with age, skin condition and shot count.
How many shots do I need for my face?
It depends on face size, skin thickness and areas of concern. Send us a photo and we'll tell you the shot count for each area in advance, based on the doctor's opinion.
Is eye Thermage safe for the eyes?
It is done with an eye-specific tip after protective eye shields are placed. Please remove contact lenses before treatment.
Does it hurt a lot?
Each shot feels briefly hot, but cooling, vibration and numbing cream reduce it. If it hurts, tell the doctor right away and the intensity can be adjusted.
Can I fly the day after treatment?
Downtime is minimal, so many people can fly the next day. Pay attention to moisturizing on the plane.
Can I have it if I have metal implants or a pacemaker?
Because it is a radiofrequency treatment, you must tell us beforehand. Depending on the type and location, treatment may not be possible or the method may need to change, so the doctor decides after examination.
Can I have it on the same day as Ulthera?
Yes. If you have both sagging and loss of firmness, many people have both on the same day. Usually Ulthera is done first, then Thermage.
How do I check that it's genuine?
Ask for a new genuine tip package to be opened in front of you, and check the authentication marks on the tip and the shot count on the device screen. Your KBEAU manager helps you check on the day.
